Y RK' cusnronme ANCHORAGEDEVICE k Application filed July 26, ms. SerialNo. 295,452.

This invention relates to containers, such as tank cars, for example,and especiallyto lined tank cars having well-pipes therein for useinfilling or emptying them of their con-- tents.

A defect of such tank cars as heretofore constructed has been that thewell-pipeha's not been suitably anchored or supported at its lower endto prevent it from being broken by strains imposed upon it in the travelof the car, and this defect has been especially serious in the case oftank cars lined with rubber or other chemical-resisting material becauseof damage to the expensive lining resulting from contact of brokenportions of the well-pipe or its mounting.

One ofmy chief objects is to correct this defect and thus to provide forthe use of well-pipes in tank cars or the like without the usual dangerof breakage of the pipe or damage to the inner surface or lining of thecar.

.Another object is to avoid abrasion of the rubber covering on thewell-pipe. A further object is to provide a resilient anchorage for anend of the well-pipe whereby the latter holds said anchorage in fixedposition.

In the preferred form of my invention I attain these objects byproviding resilient means for supporting the pipe and especially 'aresilient anchorage for the lower portion of the pipe so as to permitlimited but cushioned movement of its lower end and thus avoid breakagenotwithstanding distortion and swaying of the car in service.

Of the accompanying drawings:

Fig. 1 is a side elevation of a tank car embodying my invention in itspreferred form.

Fig. 2 is a vertical section on the line 2-.2 of Fig. 1.

Fig. 3 is a vertical section on the line 33' of Fig. 1.

In the drawing, is a railway tank car, and 11 is a rubber-lined tankmounted thereon and having the usual dome portion 12 located.

- in a central region on the top thereof and having its bottom providedwith a generally hemispherical sump 13 directly below the dome 12. Thesump has a rubber lining 14 somewhat thicker than the rubber lining ofthe other portions of the tank.

threaded into the 'member jfreelythrough suitable bolt-holes in the colupper end of the well pipe 22, and is easil Thedome;12 is formed withacircumferential restricted zone 15 near its top, and a rubber-linedpipe or the like 16 opens into the dome at said restrictedfzone; thepipe 16 normally being closed by a flanged plate or the like 17.stricted zone of the dome 12 isfiared radially and'forms a flange uponwhich a rubbercovered, centrally apertured, closure member 18 ismounted,;saidclosure member bein secured by a plurality of bolts 19. Theclosure member 18 has its central portion dished or depressed as at 20,and the central aperture therein is designated 21.

' Extendingdownwardly through the aperture 21 isa cylindrical well-pipe22 which has its inner "and outer surfaces covered with rubber. Theupper end "ofthe well-pipe 22 is threaded into a rubber-covered flangedcollar 23 theflange of which extends overyand is secured to the closure'member-18 by studbolts; 2 1-; and nuts 25, the stud-bolts being 18 andpassing A flang'edcap or plate 26 ofrubber-covered metal: is securedagainst the top face of the'collar .23 by the stud-bolts 24 and nuts 27The cap 26 provides a ciosurerfor the remove' d' 'for the filling or.emptying of the tank without disturbing the well-pipe support. I a l'Aflat cover-plate 28 is'hinged at 29 in a --pairofears30 rising from theclosure member-18;.andatlordsprotection to the exposed rubber surfacesof said'closure member and thecapl26to prevent deterioration of'therubber from exposure to the elements.

1 For supportingandjanchoring the wellpipe 22;.atits lowerend,aremovable substan itiallydiemisphefical pipe support 31 of cushtoningmaterial "preferably of a resilient v material suchas rubber, isprovided, the said support: being in the formof a plug of rubbershaped'to' fitinto and fillthe sump 13 to ap ointnearly'flush with thebottom of thetankf l p f Thepipe support 31 is [formed with an axialbore 32 extending from its top surface y Jae downward for a substantialdistance, the

said bore 32 being adapted to receive the lower end of the well-pipe 22.In continuation of the bore 32 is a coaxial bore 33 of smaller diameterextending downwardly to a point somewhat above the bottom of the pipesupport 31. At the juncture. of the coaxial bores 32 and 33 is a lippedflange or shoulder 34 adapted to engage the inner surface of the end ofthewell-pipe 22 and thus to effect the firm seating'of the latter.

The axial bore 33 communicates at its lower end with a plurality ofarcuate passages 35, 35 which are formed in the pipe support 31'andextend respectively to the upper surface thereof, the combined'capacityof the-several passages 35 being substantially the same as the capacityof the bore 33. i

The invention provides two-point support for therubber-coveredwell-pipes in rubberlined tank cars, and the yielding character pipesupport 31 permits 20 sim le secure end engaged with'said resilientmember and of the lower support insures against abrasion of the rubbercovering on the well pipe.

This embodiment of the invention in no way interferes with the fillingor emptying of the tank, which is accomplished usual manner through thewell-pipe. Being located at the lowestpoint of the tank, the

in the with a sump, a rubber block removably mounted in the sump andformed to engage a well pipe and cushion the same, and a well pipesuspended in said tank and engaging said block. v

5. In combination a mobile tank formed with a rubber lined sump, a blockresiliently supported in said sump and formed to engage a well pipe,anda well pipe engaging said-block and suspended fromthe top of saidtank.

1. In combination, a mobile tank formed with a sump, a resilient membercomprising a rubber mounted in said sump, and a wellpipe mounted in saidtank-having itslower holding the same firmly within the sump.

2. In combination, a mobile tankformed with a sump, a cushioning member'mounted in said'sump and formedwith a recess in its upper face, and a'well-pipe-mounted in said tank having its lower end removably seated insaid recess whereby thecushioning memher is held in fixed positionwithin the sump. 3. A combination as defined in claim'2 in which thecushioning member is formed with a passage communicating with saidrecess V and the interior of the tank.
